Muon tomography has become in the last few years one of the most widely studied applications of Laser - Wakefield Acceleration (LWFA). In order to create a reliable muon source, we stabilized the electron beams energy gain to high-energies peaking between 6 and 8 GeV and integrated charge of hundreds of pC. To ensure the detection of muon beams, heavy shielding was installed. The detectors...

For a long time, ternary particle emission in low-energy fission has suggested the presence of non-equilibrium dynamics within the neck at the time of scission. We report a microscopic framework that follows the time evolution of nucleon densities in the neck of the fissioning system during the transition from saddle to scission. The shape evolution is modeled using multi-dimensional Langevin...

Early detection of breast cancer remains a crucial objective in modern medicine. High-sensitive X-ray imaging based on Talbot-Lau interferometry offers enhanced soft-tissue contrast compared to conventional mammography, making it a promising tool for non-invasive diagnostics. This work explores the integration of Convolutional Neural Networks (CNNs) with high-sensitivity Talbot-Lau imaging to...

The study of particle (n, p, α, and γ) emission in fission phenomena is crucial to understand the involved timescales, the energy dissipation, and the underlying mechanisms of the process. Among these, neutron emission is one of the most experimentally exploited process. Earlier studies of neutron-neutron (n–n) correlations were primarily focused on scission neutrons. More recent measurements...

In the biomedical field, several applications for the High Power Laser Systems are proposed. Delivering a high dose in a very short time and understanding the biomolecular effects of radiation is a challenge with implications for clinical translation. Biological systems are impacted differently by various radiation dose-rates. Finding new ways to detect dose-rate effects as early as possible...

A theoretical model based on the Large Scale Shell Model is employed for the study of low-lying 1+ and 2+ states in medium mass nuclei. The code NuShellX@MSU is used for the study of low-lying M1 modes arising from the interference between orbital and spin magnetic moments in even-even Chromium nuclei.

Nanostructured targets significantly enhance laser-matter interaction by coupling the laser pulse into the target, due to the increased surface area, resulting in higher proton energy cut-off, yield, X-ray or gamma ray emission. However, enhanced coupling is highly dependent on the correlation of the target parameters to the laser pulse characteristics (as laser contrast, wavelength, and pulse...

We report the experimental demonstration of double-layer foam targets (DLFTs), consisting of ultra-low-density carbon foam deposited on thin aluminum foils, for enhanced laser-driven proton acceleration in the TNSA regime. Compared to bare aluminum targets, DLFTs exhibit improved laser absorption and modified preplasma formation, resulting in increased proton cut-off energy and particle flux....

It is presented the first-hand experience of Large Language Models (LLM) use in the early stages of research activity - the PhD studies. For the past 2 years, LLMs have been released and suffered wide-spread integration within the workflow of almost all industrial and research domains. Here, I present the positive and negative impact of LLMs during my (and my fellow colleagues) studies such as...

The abundances of the light elements can be spectroscopically determined by observing the low-metallicity stars. Usually, those measurements are in agreement with the Big Bang Nucleosynthesis predictions. In particular, the measured abundance of Li7 is 3-4 times lower than expected, discrepancy known as the “cosmological Li problem”.

PADC detectors are made from a thermosetting polymer used as solid-state nuclear track detectors (SSNTDs), being directly sensitive to charged particles and indirectly to neutrons. For this reason, this type of detector is ideal for use at ELI-NP, due to its sensitivity to a wide range of particles and radiation types. A second reason for using these detectors at ELI-NP is the fact that they...

The “peeler” scheme, originally proposed for proton acceleration, involves irradiating the narrow (sub-micron) side of a solid tape target. The large number of extracted electrons travel to the target rear and create a strong space charge field, which efficiently accelerates hydrogen ions found in the contaminant layer. However, the energy spectrum of higher Z (such as carbon) ion bunches is...

Understanding how elements are formed in the universe requires a detailed knowledge of the nuclear reactions that govern nucleosynthesis. Particle capture and photo-absorption reactions are particularly important, as they compete to build up or dismantle nuclei in stellar and explosive environments. The probabilities of these reactions are governed by cross-sections, which in turn depend...
